Taken it out twice, will post pics in a bit (haven't got vid yet). Running 91 octane (could of gotten 93 octane, but that wasn't at local station). At my house I get 135psi, where I ride I get around 160psi. So far I've been using a 10hp boost (with nitrous and fuel together, so that it doesn't lean out). No pre-detonation or anything weird with the engine. I have it set so the switch is pressed when the throttle is fully depressed and works great! Very controlled, though pulls a lot more than I'm used to. You could say it unlocks the potential of my 14/19 Solas, which is way over pitched when not boosting. $13 for 2.5lbs, and I seem to burn about 2lbs/hour, though still need to play with it. The original fuel pump burned out when I was testing the electronics at home, so got a new one and then tidied everything up. I paid $500 for the kit, which I think was a total rip off and could be done a LOT cheaper, though I wanted to make sure I had everything needed instead of making a custom kit like originally planned.
All in all, I couldn't be happier. Probably one of the cheapest alternatives to more horsepower, and since I ride at altitude, I don't have to worry about over working the engine since my boost is set to compensate for the ~20% power loss I feel.
